              Tour “Đại lộ QC” – Hành trình khám phá nghề kiểm thử cùng ST

              Chào mừng bạn đến với series “Chuyện ngành chuyện nghề - Team QC”, nơi chúng mình kể lại những câu chuyện thật nhất về hành trình làm nghề, những niềm vui và… những pha “dở khóc dở cười” phía sau mỗi bản build. Để bắt đầu nghề QC thì không khó, nhưng để trở thành QC giỏi không phải điều dễ dàng. Trước khi lên đường khám phá, hãy cùng mình “bóc tem” một vài hiểu lầm kinh điển về nghề QC nhé! Có phải bạn đã từng nghĩ rằng: - Ai cũng học QC được? - Ai cũng làm QC được? - QC chỉ cần bấm bấm test test và report bug? Vậy thì hôm nay, hãy cùng gặp gỡ hướng dẫn viên du lịch - Nguyễn Quang Vũ (QC Team)  - người sẽ đưa các bạn tham quan một con đường huyền thoại mang tên “Đại lộ QC”. Thắt dây an toàn, cầm vé trên tay và chúng ta sẽ xuất phát ! Km 0 – Cổng “Khởi Đầu” Trước khi trở thành “người gác cổng chất lượng”, mỗi QC đều bắt đầu bằng giai đoạn… bấm mọi thứ có thể bấm. Đây là lúc bạn làm quen sản phẩm, hiểu người dùng, và tập làm bạn với bug. Bạn sẽ cần mô phỏng hành vi người dùng, bấm - nhìn - ghi để xem sản phẩm có chạy đúng như mong đợi. Tưởng đơn giản mà không hề đơn giản: phải quan sát và đặt câu hỏi đúng chỗ. ❓ Vì sao ai cũng nên dừng ở đây? - Đây là nơi hình thành tư duy kiểm thử và hiểu quy trình phát triển. Như học lái xe: nắm vững gương, đèn, phanh rồi mới tính chuyện đổ đèo. 💡 Mẹo sống còn: - Học cách viết test case rõ ràng. - Biết phân biệt bug vs feature (phao cứu sinh tình bạn với dev). - Ghi chép gọn gàng, ảnh/chụp màn hình là tem visa cho mỗi phát hiện. 🔌 Trạm tiếp năng lượng:  Kiểm thử các luồng “hơi đời” như mất mạng, pin 2%, nhập emoji vào ô số, đổi ngôn ngữ giữa chừng. Đây là nơi rất kích thích sự tò mò của các bạn! Km 10 – Ngã rẽ “Phát Triển” Ở Km 10, bạn chọn đường mình muốn đi, miễn đi sâu một nhánh: ⬅️ Nếu bạn chọn làn trái: Automation Test, nơi còn gọi là “Làng Code”. Bạn sẽ nhận được: - Bản đồ: biết code và tư duy code để tự động hoá những thứ lặp lại. - Điểm check-in: Script chạy qua đêm, CI/CD, báo cáo xanh lè sáng sớm. - Quà lưu niệm: Khả năng đọc API, log, mock data, dựng pipeline nhoáng cái là xong. ➡️ Còn nếu bạn chọn làn phải: Performance Test, được ví như “Thung lũng Hạ Tầng”. Bạn sẽ có 1 chuyến trải nghiệm thú vị khác: - Bản đồ: cần hiểu hệ thống, kiến trúc, infra logic; đo độ bền, độ tải, độ chịu nhiệt. - Điểm check-in: JMeter/K6, profiling, bottleneck, tuning database. - Quà lưu niệm: Biểu đồ đẹp như tranh, nơi có lời giải cho câu hỏi vì sao “chạy một mình thì nhanh, có người xem livestream thì… khựng”. 📍 Nguyên tắc vàng của Km 10:  “Biết nhiều một chút, nhưng phải biết sâu một phần.” Có chiều rộng để phối hợp, có chiều sâu để gánh trách nhiệm.  Ở đoạn đường này, QC không chỉ tìm lỗi mà còn đề xuất cải tiến, thiết kế trải nghiệm, góp phần tạo ra chất lượng toàn diện. Related Blogs: > Must-Have Tools for Business Analyst > How to Step Out of the “Forwarder” Shadow? Km 25 – Quảng trường “Tư Duy Làm Chủ” Sau một thời gian quen tay với việc test bug và viết test case, bạn sẽ nhận ra: QC không chỉ là người tìm lỗi, mà còn là người giúp sản phẩm tốt lên từng ngày. Đây là lúc bạn bắt đầu bước ra khỏi “vùng kiểm thử” quen thuộc để nhìn sản phẩm ở góc độ rộng hơn: người dùng đang cần gì, team đang gặp khó ở đâu, và giá trị thực mà sản phẩm mang lại là gì. Bạn bắt đầu làm gì? - Điều phối nhịp sprint, push tiến độ, sắp hàng ưu tiên, nhìn rủi ro bằng ống nhòm và nói chuyện người dùng như hàng xóm thân. ❓ Để ở lại quảng trường này lâu, bạn cần: - Hiểu quy trình từ yêu cầu → phát triển → phát hành. - Nắm sản phẩm & người dùng hơn cả tên thú cưng nhà mình. - “Thấu” team sản xuất: dev cần gì, design lo gì, PM sợ gì, khách hàng kỳ vọng gì. Bài học đường dài: QC giỏi có “la bàn hệ thống” - biết hướng về giá trị người dùng, không chỉ về “màu xanh của report”. Km 40 – Ghé thăm đặc khu “ST QC”  và Về đích  Sau khi băng qua những chặng đường đầy bug và deadline, mời bạn ghé trạm dừng chân tại đặc khu “ST QC”. Đây là nơi những người làm kiểm thử thật sự trưởng thành và tìm thấy hướng đi cho riêng mình. Tại đây, bạn sẽ được “đi tour” qua đủ mọi cung đường nghề QC. Từ Manual Test đến Automation hay Performance Testing, thử sức để biết bản thân phù hợp với hướng nào. Ở ST luôn được khuyến khích học hỏi, có mentor tận tình chỉ đường, và rất nhiều ngã rẽ nghề nghiệp cho bạn mở rộng: từ QA, QC Technical Lead, cho đến BA hay PM. Chúng mình tin vào văn hoá “đi thực chiến trước, giáo trình hoá sau”. Nghĩa là không học để biết, mà học để dùng, để làm cho sản phẩm tốt hơn mỗi ngày. Vé VIP cho người mới Mentor thâm niên luôn đồng hành cùng bạn.Starter Kit “xịn”: test template, bug report, release checklist, sample pipeline.Nhớ câu thần chú:  “Chất lượng là thói quen mỗi ngày, không phải phép màu cuối sprint.” Phụ lục cho hành khách yêu khám phá. Trên “Đại lộ QC”, bạn sẽ bắt gặp những biển báo quen thuộc: ⚠️ Cảnh báo dốc: Thiếu kiên trì, kỷ luật hay tư duy hệ thống rất dễ tụt dốc.🆘 Làn khẩn cấp: Khi hoang mang, hãy quay lại acceptance criteria và dữ liệu gốc.🏥 Trạm y tế: Nếu burnout, dừng lại nghỉ, xem lại ưu tiên và xin hỗ trợ đoàn mình không ai bị bỏ lại. Combo “Túi đồ nghề QC” Checklist / Test Case, Mindmap risk, Template Bug Report, Common Edge Case, Script tiện tay. Trang bị đủ hành trang để bạn tự tin băng qua mọi sprint nhé. “Đại lộ QC” không phải đường cao tốc thẳng tắp, mà nó còn có dốc, có đèo, có khúc cua tay áo. Nhưng đổi lại là một hành trình đáng nhớ: sản phẩm chạy mượt, người dùng mỉm cười, team tin tưởng nhau hơn. Con đường này dễ xuất phát nhưng khó về đích. Vì thế hãy  luôn vững tin với chiếc vé mang tên kiên trì, kỷ luật, tư duy hệ thống, chúng sẽ giúp bạn đến được nơi mình muốn. Nếu bạn đã sẵn sàng, mời lên xe chuyến sau. Hướng dẫn viên “trái ngành” vẫn ở đây, tay trái cầm bản đồ, tay phải cầm… checklist. Hẹn gặp bạn ở một cột mốc mới trên Đại lộ QC!
